Any utilities that are damaged during the course of the work shall be repaired or replaced to the satisfaction of the engineer at the contractor s expense CLEARING AND GRUBBING Prior to topsoil stripping, all topsoil shall be made to be free from surface vegetation over six inches in height, trash, stones, and all other debris by clearing and grubbing. The Engineer will establish the limits for clearing and grubbing and designate all trees, shrubs, plants and other items that are to be removed. Unless otherwise specified, all material cleared and grubbed shall be disposed of at the City of Fargo landfill TREE REMOVAL The Engineer will mark all trees that are to be removed; the Contractor shall not remove any tree not marked for removal.
